Grow up the farclip in C#

Hi, simple question here.
How to grow the camera far clip in C# ?
I’ve a script that require an higher far clip ONLY when you find all the necessary stuffs.

Here a piece of my code :

IEnumerator PlaySound(){
		AudioListener.pause = true;
		audio.clip = DANCE;
		audio.ignoreListenerPause = true;
		audio.Play ();
		RenderSettings.fog = revertFogState; 

//Grow Camera Farclip here.
		yield return new WaitForSeconds(audio.clip.length);
		AudioListener.pause = false;
